Double-sensitive fuse is an important accessory for over-current protection of oil-immersed transformers in power distribution systems. It is used with plug-in fuses and backup fuses to form a "double-fuse protection" solution. The double-sensitive fuse protects the low-voltage side of the transformer from faults or overloads in terms of current and temperature, and prevents the transformer from rising in humidity due to overload or excessive ambient temperature. The double-sensitive fuse is installed into the plug-in fuse, which is quick to install, easy to replace, and reliable in operation.
The plug-in fuse holder is mainly used as an important accessory for overcurrent protection of box-type transformers. By installing the matching fuse inside, the transformer can be protected from many aspects, such as current size, oil temperature, etc. Plug-in fuses are simple to install, reliable in operation, and easy to replace the fuse. Widely used in transformer high voltage side protection.
The plug-in fuse fuse cartridge can be installed with different types of fuses according to the protection conditions. Such as current-type fuses, dual-sensitive fuses, dual-factor fuses, and high-current overload fuses.
The backup fuse is used in American box-type transformers and is the main component that provides over-current protection for American box-type transformers.
